Honey Tree Holdings / This man still owed me money for the job

When I worked for Honey Tree Holdings, I didn’t face any problems. But I resigned in the end of September. This man owed me money for August and September. I have finished all the work before I resigned. The owner didn’t have any pretensions, so I waited for the check. Two months passed and the owner didn’t even call me. I am very upset that this man doesn’t want to pay me, when I have worked hardly.
